CONVEYING APPLIANCE.

SPECIFICATION forming part of Letters Patent No. 667,440, dated February5, 1901.

Application filed November 2, 1900. Serial No. 85,222. (No model.)

To all whom, it may concern.-

Be it known that I, WILLIAM S. HALSEY, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a certain new anduseful Improvement in Conveying Appliances, of which improvement thefollowing is a specification.

The object of my invention is to provide a simple, convenient, andinexpensive appliance by the employment of which a plurality of skelps,bars, or other metal articles may be picked up ata desired point orpoints and conveyed to and delivered at a desired point or points.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a side view in elevation of aconveying appliance illustrating an application of my invention; Fig. 2,a similar view, on an enlarged scale, of the middle portion of the same;Fig. 3, a transverse section taken adjacent to the center, and Fig. 4 aside View in elevation of the scale-case detached.

In the practice of my invention I provide a substantial main frame 1,which is preferably, as shown, in the form of a channelbeam having itsflanges turned downwardly and is stiffened and strengthened by trussrods2, passing through eyes in central struts 3, bolted to the flanges ofthe beam at each side of its middle portion and clamped by nuts engagingscrew-threads on their ends to sockets at, fixed to the flanges of thebeam. The skelps or other metal articles which are to be handled by themachine are supported upon a plurality of carriers, which are metal barshaving a lower arm 5, standing normally in a substantially horizontalposition, and an upper arm 6, which adjacent to the lower arm 5 is at orabout a right angle thereto and is for the remainder of its lengthextended outwardly or away from the adjacent end of the arm 5. The upperarms 6 of the carriers are pivoted by bolts 7 to hangers 8, secured toone of the flanges of the beam 1, and their upper ends are coupled bylinks 9 to arms 10, fixed upon a dumping-shaft 11, which is journaled inthe upper portions of the hangers 8. A dumping-lever 12, having an eyein its upper end for the connection of an operating cord orchain, isfixed upon the shaft 11, preferably at the middle thereof.

The carriers are, when unloaded, brought to and normally held inposition with their lower arms 5 standing substantially horizontally bycounterbalances 13, fixed upon arms 14, projecting outwardly from theupper arms 6, adjacent to their pivots 7. The links 9 normally standwith their end coupling-pins in line with the axis of the dumping-shaft11, and when a load is placed upon the lower arms 5, tending to depressthe outer end thereof, the carrier is locked in position by thetoggle-joint action of the links 9 and dumping-shaft arms 10. By movingthe upper end of the dumping-lever 12 outwardly the links 9 and arms aremoved out of line and the lower arms 5 are depressed by the weight ofthe load thereon, thus permitting the same to be dropped at any desiredpoint. Upon the release of the load from the arms 5 the counterbalances13 return them to their normal horizontal position, in which they arelocked by the toggle-joint connections to the clampin -shaft abovedescribed.

The main frame 1 is connected at its center by a bolt 15 to a standard16, which in the instance shown extends upwardly into the box or case 17of a scale or weighing mechanism of any known and preferredconstruction, which may desirably be connected to the appliance,although not essential thereto, for the purpose of enabling the weightof the load to be ascertained beforeits delivery at a dc sired point.The weighing mechanism does not in and of itself constitute part of mypresent invention and need not therefore be herein at length set forth.The upper end of the standard 16 is coupled to an unequal armed lever18, the shorter arm of which is pivoted by a bolt 19 to the scale-case17 and the longer arm coupled by a link 26 to a scale-beam 20, carryinga weight or pea 21. The scale-case is provided at its top with ahorizontal bar 22, fixed to standards 23 on the ends of the case, saidbar providing for the attachment of the main frame 1, in this instancethrough the intermediate connected scale-case, to any suitable andpreferred traveling conveyor, which is shown as a fluid-pressurecylinder 24, the piston-rod 25 of which is connected to the bar 22 ofthe case and which is adapted to raise and lower the main frame and itsload and to traverse longitudinally therewith in the ordinary mannerupon an elevated track or to be moved by a traveling crane. When aWeighing mechanism is not employed, the main frame is connectedcentrally to the travcling conveyer in any suitable known manner.

In operation a load of any desired number of 'skelps or other articlesis placed upon the lowerarms 5 of the carriers, moved by the conveyingappliance to the desired point of delivery, and there deposited by themovement of the dumping-lever, as above explained. The material to beconveyed may be either picked up from a scale on which it has beenweighed or if the appliance is, as shown, provided with a connectedWeighing mechanism it may be Weighed when resting on the carriers.

I-claim as my invention and desire to secure by Letters Patent 1. In aconveying appliance, the combination of a main frame, a plurality ofcarriers pivotally connected thereto, a dumping-shaft jonrnaled on themain frame, connections coupling the carriers and dumping-shaft, and adumping-lever connected to the dumpingshaft.

2. In a conveying appliance, the combination of a main frame, aplurality of carriers pivotally connected thereto, a dumping-shaftjournaled on the main frame, toggle-joint connections coupling thecarriers and dumpingshaft, and a dumping-lever connected to thedumping-shaft.

3. In a conveying appliance, the combination of main frame, a pluralityof carriers pivotally connected thereto, a dum ping-shaft journaled onthe main frame, connections coupling the carriers and dumping shaft,counterbalances fixed to arms on the carriers, and a dumping-leverconnected to the dumping-shaft.

4. In a conveying appliance, the combination of a metal-bar main frame,lateral trussrods connected thereto, a plurality of carriers "pivotallyconnected to the main frame at one side thereof, a dumping-shaftjournaled on the opposite side thereof, connections coupling thecarriers and dumping-shaft, and a dumping-lever connected to thedumpingshaft.

5. In a conveying appliance, the combination of a metal-bar main frame,a plurality of carriers, each having a lower supportingarm and an upperarm at an angle thereto, pivot-bolts coupling said carriers to hangersupon one side of the main frame, counterbalances fixed to the upper armsof the carriers, a dumping-shaft journaled in bearings on the oppositeside of said frame and having an arm opposite each of the carriers,links coupling the upper arms of the carriers to the arms of thedumping-shaft and having their end pivots normally in line one with theother and with the axis of the dumping-shaft, and a dumping-leverconnected to the dumpingshaft.
